Predicting a positive response to physiotherapy treatments for patients in the MOA Trial
Principal Investigators: Cathy Chapple (PhD Candidate), Dr Alexis Wright (PhD Candidate)
Co-Investigators: Associate Professor J Haxby Abbott (Orthopaedic Surgery, Department of Surgical Sciences), Professor G David Baxter (School of Physiotherapy), Associate Professor John Dockerty (Department of Preventive & Social Medicine), Professor Helen Nicholson (Otago School of Medical Sciences)
Objective: To determine clinical prognostic factors that maximize the accuracy of identifying patients with hip or knee osteoarthritis likely to demonstrate a favorable response to physiotherapy treatment.
Design: Prognostic studies nested within the MOA Trial RCT.
Methods: Participants in the MOA Trial were assessed at baseline in order to later determine which patient characteristics, when clustered together, were most predictive of a favorable response to physical therapy treatment. Positive responders to the MOA Trial physiotherapy interventions were identified after one year.
Conclusions: Both the hip study (Dr Lexie Wright) and the knee study (Cathy Chapple) found clustered combinations of clinical findings that indicate the probability of a favorable response to physiotherapy treatment in patients with OA.
